Description

Technical Field

[0001] This invention relates to the field of cable tray technology, specifically to a cable tray installation structure. Background Technology

[0002] Cable trays are rigid structural systems used to support and protect cables, widely used in construction, power, and communication fields. They are mainly used to support cable lines. Common cable trays include trough type, tray type, and ladder type. For example, the quick-installation cable tray with announcement number CN221669450U relates to the field of cable tray technology. This quick-installation cable tray includes a fixed top plate, a fixed bottom plate that is slidably connected to the inside of the fixed top plate, a protrusion that is fixedly connected to the surface of the fixed top plate, and a threaded rod that is threaded inside the protrusion. A fixing block is fixedly connected to the surface of the fixed bottom plate, and a sliding groove is opened on the front surface of the fixed bottom plate. A fixing device is set inside the sliding groove. With this quick-installation cable tray, the operator presses the pressure plate upwards, and the pressure plate drives the sliding rod and slider to slide upwards. The slider slides upwards, causing the triangular locking block to slide upwards and disengage from the fixing groove, thus completing the disassembly of two cable trays. The operation is simpler, and it is easier for operators to disassemble and repair the cable trays in case of subsequent damage, improving the convenience of cable tray disassembly and installation.

[0003] For example, a high-strength steel cable tray with announcement number CN112271665B includes a cable tray body one and a cable tray body two. The cable tray body one includes a first flat plate and two first vertical plates, while the cable tray body two includes a second flat plate and two second vertical plates. Two lower fixing mechanisms are fixedly installed on the cable tray body one, located between the two first vertical plates. Two upper fixing mechanisms are fixedly installed on the cable tray body two, located between the two second vertical plates. This cable tray can simultaneously install and fix multiple cables using multiple bolts for connection and fixation. It has high overall strength, is easy to install and disassemble, and is convenient for maintenance. This invention uses a cable tray processing device to process the steel plate quickly and conveniently, greatly improving the production efficiency of the cable tray. This cable tray is suitable for mass production. However, the installation of the above-mentioned cable tray still has the following disadvantages in practice:

[0004] 1. Traditional cable trays are not convenient for cable installation and restraint during use. They only have a simple cable restraint structure, which can easily cause adjacent cables to become misaligned when pulling the cables during subsequent maintenance.

[0005] 2. Furthermore, the cables are kept inside the cable tray for extended periods. Although not completely sealed, the heat dissipation effect is poor. When the cable temperature is high during use, the cable tray itself does not have an active heat dissipation structure, resulting in low heat dissipation efficiency and affecting the use of the cables.

[0006] To address the aforementioned issues, there is an urgent need for innovative design based on the existing cable tray installation structure. Summary of the Invention

[0007] The purpose of this invention is to provide a cable tray installation structure to solve the problems mentioned in the background art, such as the inconvenience of cable installation and positioning in traditional cable trays, the lack of active heat dissipation structure in the cable trays themselves, resulting in low heat dissipation efficiency and affecting cable use.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a cable tray installation structure, including a cable trough, with lifting rods fixed on both sides of the cable trough, and the outer side of the lifting rods being connected to the top of a cover plate through an adjustment mechanism, and the cover plate being separated from and in contact with the cable trough by lifting and lowering, and heat dissipation holes being provided at the bottom of the cable trough, the heat dissipation holes being equally spaced, and a filter screen being fixed on the inner side of the heat dissipation holes;

[0009] It also includes: a limiting component, which is disposed inside the cable groove. The limiting component is used to fix and limit the cable, and a heat dissipation mechanism is provided at the bottom of the limiting component. The heat dissipation mechanism is connected to the heat dissipation hole.

[0010] Preferably, the adjusting mechanism includes a movable cylinder sleeved outside one of the lifting rods, and the lifting rods and the movable cylinder are rotatably connected. The outer surface of the movable cylinder is provided with a threaded groove, and the movable cylinder and one of the connecting blocks are threadedly connected. When the movable cylinder is rotated, the connecting block can be driven to rise and fall through the threaded transmission with the connecting block.

[0011] Preferably, the adjusting mechanism further includes a fixed cylinder sleeved on the outside of another lifting rod, and the fixed cylinder and the lifting rod are fixedly connected, and the outer side of the fixed cylinder is slidably connected to another connecting block, which can slide on the fixed cylinder, thereby driving the cover plate to rise and fall.

[0012] Preferably, the two connecting blocks are fixedly connected by a fixing rod, and the bottom of the fixing rod is fixedly connected to the cover plate. The fixing rod has a "T" shaped structure, and the cover plate separates from and contacts the cable trough by lifting and lowering, which is convenient to operate.

[0013] Preferably, the limiting component includes a tray fixed inside the cable trough. The trays are evenly spaced, and a fixed cavity is provided inside the tray. A movable plate is provided inside the fixed cavity. The evenly spaced trays facilitate the separate placement of different cables.

[0014] Preferably, the movable plate forms a sliding structure through the fixed cavity and the support plate, and both the support plate and the movable plate have arc-shaped cross sections. A spring is provided between the movable plate and the fixed cavity so that the cable can be limited when the movable plate slides out.

[0015] Preferably, the movable plate is fixedly connected to one end of the spring and one end of the traction rope on the side with the spring, and the other end of the traction rope is wound around the movable drum. The traction rope slides through the cover plate and can be wound up synchronously when the movable drum is rotated.

[0016] Preferably, the heat dissipation mechanism includes a heat-conducting rod fixed to the bottom of the tray, and the bottom of the heat-conducting rod is connected to a shape memory alloy, and the shape memory alloy is in close contact with the inner bottom surface of the cable groove, so that the heat of the cable can be transferred to the shape memory alloy through the heat-conducting rod.

[0017] Preferably, the shape memory alloy and the heat dissipation holes are distributed in a one-to-one correspondence, and the shape memory alloy bends when heated, and the two ends of the shape memory alloy are fixedly connected to the two ends of the connecting rope. When the shape memory alloy is heated, it releases the blockage of the heat dissipation holes to facilitate heat dissipation.

[0018] Preferably, a fixing block is fixed in the middle of the connecting rope, and the fixing block is in close contact with the lower end face of the filter screen. Both ends of the connecting rope slide through the cable groove. The fixing block knocks on the filter screen to clean the dust.

[0019] Compared with the prior art, the beneficial effects of the present invention are: the cable tray installation structure can automatically limit the cable position after the cable tray cover is closed, ensuring its stability, and will not cause adjacent cables to become disordered when pulling the cable during subsequent maintenance. Furthermore, when the internal temperature of the cable tray is too high, it can automatically trigger the heat dissipation mechanism to dissipate heat. The specific details are as follows:

[0020] 1. By rotating the movable cylinder and driving it through the threaded connection with the connecting block, the fixed rod can drive another connecting block to slide on the fixed cylinder, thereby causing the cover plate to descend and close with the cable trough, which can quickly and conveniently connect the cable trough and the cover plate.

[0021] 2. Rotate the movable drum to wind up the traction rope. When the traction rope is pulled, it can drive the movable plate to slide in the fixed cavity, so that the movable plate covers the top of the support plate, thereby limiting the cable and ensuring its stable position. When the cable is pulled later, it can only move inside the support plate and the movable plate.

[0022] 3. The heat from the cable is transferred to the shape memory alloy through the heat-conducting rod. Therefore, the shape memory alloy can bend when heated, thus removing the obstruction of the heat dissipation holes and allowing the heat in the cable groove to dissipate. When the shape memory alloy bends, it can pull the connecting rope to move, causing the fixing block to knock the dust off the filter screen. Attached Figure Description

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figures 1-9 The present invention provides the following technical solution:

[0035] Example 1: To address the problems existing in the prior art, this example provides a cable tray installation structure, including a cable trough 1. Lifting rods 2 are fixed to both sides of the cable trough 1, and the outer sides of the lifting rods 2 are connected to the top of a cover plate 7 via an adjustment mechanism. The cover plate 7 separates from and contacts the cable trough 1 through lifting and lowering. Heat dissipation holes 8 are provided at the bottom of the cable trough 1, with equal spacing between them, and a filter screen 9 is fixed to the inner side of each heat dissipation hole 8. The structure also includes a limiting component, disposed inside the cable trough 1, for limiting... The component is used to fix and limit the cable, and the bottom of the limiting component is provided with a heat dissipation mechanism, which is connected to the heat dissipation hole 8. First, the cable tray 1 can be installed in the designated position by the hoisting rod 2. Then, the cable to be laid is passed through the inside of the cable tray 1. The cable is placed separately by the support plate 10. Then, the cover plate 7 is placed on the cable tray 1 to complete the installation of the cable tray and the cable. The cable tray 1 is provided with multiple sections at equal intervals. Different cable trays 1 need to be installed separately. The long cable can be installed by connecting adjacent cable trays 1.

[0036] In most existing cable trays, the cover plate 7 and the cable trough 1 are separate, making their installation and connection inconvenient. Figures 1-3 As shown, the adjustment mechanism includes a movable cylinder 3 sleeved outside one of the lifting rods 2, and the lifting rod 2 and the movable cylinder 3 are rotatably connected. The outer surface of the movable cylinder 3 is provided with a threaded groove, and the movable cylinder 3 and one of the connecting blocks 4 are threadedly connected. The adjustment mechanism also includes a fixed cylinder 6 sleeved outside the other lifting rod 2, and the fixed cylinder 6 and the lifting rod 2 are fixedly connected. The outer side of the fixed cylinder 6 is slidably connected to the other connecting block 4. The two connecting blocks 4 are fixedly connected by a fixed rod 5, and the bottom of the fixed rod 5 is fixedly connected to the cover plate 7. The fixed rod 5 has a "T" shaped structure. After the cable is installed, rotating the movable cylinder 3, through the threaded transmission with the connecting block 4, can drive the other connecting block 4 to slide on the fixed cylinder 6 through the fixed rod 5, thereby driving the cover plate 7 to descend and close with the cable trough 1, thus realizing the installation of the cable tray.

[0037] Example 2: Existing cable trays are not convenient for cable installation and restraint during use, only having a simple cable restraint structure. This can easily cause adjacent cables to become misaligned when pulling cables during subsequent maintenance. Therefore, this example uses the following technical solution: Figure 2 and Figures 4-6As shown, the limiting assembly includes a support plate 10 fixed inside the cable trough 1. The support plates 10 are evenly spaced, and a fixed cavity 11 is formed inside the support plate 10. A movable plate 12 is provided inside the fixed cavity 11. The movable plate 12 forms a sliding structure with the support plate 10 through the fixed cavity 11. Both the support plate 10 and the movable plate 12 have arc-shaped cross-sections, and a spring is provided between the movable plate 12 and the fixed cavity 11. The side of the movable plate 12 with the spring is fixedly connected to one end of a traction rope 13, and the other end of the traction rope 13 is wound around the movable cylinder 3. The traction rope 13 slides through the cover plate 7. When the movable cylinder 3 is rotated, it causes the cover plate 7 to descend, and the other end of the traction rope 13 is rotated. The traction rope 13 can be wound up at the upper end of the movable cylinder 3. When the traction rope 13 is pulled, it can drive the movable plate 12 to slide in the fixed cavity 11. Since the height of the movable cylinder 3 does not change, it can pull the traction rope 13 to drive the movable plate 12 to rotate when rotating. After the cover plate 7 is closed, the movable plate 12 can be pulled out to cover the support plate 10, thereby limiting the cable and ensuring its stable position. When the cable is pulled later, it can only move inside the support plate 10 and the movable plate 12. When the cover plate 7 is opened, the movable cylinder 3 releases the pull on the traction rope 13. In this way, the elasticity of the spring can drive the movable plate 12 to retract into the fixed cavity 11, thereby releasing the limitation on the cable.

[0038] Example 3: Existing cables are stored inside cable trays for extended periods. Although not completely sealed, their heat dissipation is poor. When the cable temperature is high during use, the cable tray itself lacks a proper heat dissipation structure, resulting in low heat removal efficiency and affecting cable performance. Therefore, this example addresses this issue through the following technical solution: Figures 7-9As shown, the heat dissipation mechanism includes a heat-conducting rod 14 fixed to the bottom of the support plate 10, and a shape memory alloy 15 connected to the bottom of the heat-conducting rod 14. The shape memory alloy 15 is in close contact with the inner bottom surface of the cable trough 1. The shape memory alloy 15 and the heat dissipation holes 8 are distributed one-to-one. The shape memory alloy 15 bends when heated, and both ends of the shape memory alloy 15 are fixedly connected to both ends of the connecting rope 16. A fixing block 17 is fixed in the middle of the connecting rope 16, and the fixing block 17 is in close contact with the lower end surface of the filter screen 9. Both ends of the connecting rope 16 slide through the cable trough 1. When the cable temperature is too high during use, the heat will be transferred to the shape memory alloy 15 through the heat-conducting rod 14. The shape memory alloy 15 is thermoelastic and martensitic. The shape memory effect is achieved through phase transition and its inverse. Therefore, the shape memory alloy 15 can bend when heated, thus removing the obstruction of the heat dissipation hole 8. The heat in the cable trough 1 can be dissipated, ensuring the normal use of the cable. After the heat in the cable trough 1 returns to normal, the shape memory alloy 15 can also return to its flat state, sealing the heat dissipation hole 8 and preventing external dust from entering. When the shape memory alloy 15 bends, it can pull the connecting rope 16 to move. When the connecting rope 16 is stretched, it drives the fixing block 17 to knock the dust off the surface of the filter screen 9, improving the heat dissipation efficiency. In addition, each section or every other section of the cable trough 1 is equipped with a heat dissipation mechanism, so the long cable can be cooled in sections to ensure its normal operation.

[0039] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
